Cutting PTFE Tubing

We have always cut PTFE tubing or sleeves for various medical or electronics applications. This is one of the more difficult tasks depending on the specifications. This tubing naturally has a "coiled" memory to it because it was spooled after the extruding process. So holding straight cut ends, particularly on longer length parts has some real challenges. Another challenge is the maintaining the I.D. and O.D. integrity. This tubing is thin wall and can easily collapse. Not quite as bad as polyimide tubing, but it is prone to collapse and kink. Tooling is critical and we have hours and hours in developing the best tools to cut this material so that the finished parts fall within the specifications of our customers.
